Maintaining ecosystem function by restoring forest biodiversity: reviewing decision-support tools that link biology, hydrology and geochemistry
Not all forest models are applicable to a meta-modelling approach. Hence, the objective of the research presented here was to identify and compare the available forest models already being used in research, and to evaluate ... -
Más allá de los modelos de crecimiento: modelos ecológicos híbridos en el contexto del manejo forestal sostenible
El desafío actual en el manejo forestal es la planificación de suministros sostenibles de madera y otros valores forestales, a la vez que se preserva la integridad del ecosistema forestal. En conse- cuencia, el uso de ... -
Meat waste as feedstock for home composting: effects on the process and quality of compost
Home composting is a powerful tool, which is spreading in different parts of the world, to reduce the generation of municipal waste. However, there is debate concerning the appropriateness, in terms of domestic hygiene and ... -
Metabolismo del azufre en la simbiosis guisante - rhizobium
Las leguminosas constituyen un cultivo importante para la agricultura sostenible, debido en parte a su capacidad para fijar el N atmosférico en simbiosis con bacterias del suelo mediante la fijación biológica de nitrógeno ... -
Modelling the management of forest ecosystems: importance of wood decomposition
Scarce and uncertain data on woody debris decomposition rates are available for calibrating forest ecosystem models, owing to the difficulty of their empirical estimations. Using field data from three experimental sites which ... -
Modelos ecológicos: descripción, explicación y predición
Los ecosistemas son, por definición, complejos sistemas en los que factores biológicos, climáticos y geológicos se combinan con factores sociales, políticos y económicos para producir una serie de procesos ambientales que ... -
Multi-scale approach to forest functioning of Pinus sylvestris L. and Fagus sylvatica L. mixtures of the Pyrenees under global change
Hoy en día, los bosques mixtos son cada vez más reconocidos como superiores a los bosques puros en cuanto a la provisión de una completa gama de bienes y servicios ecosistémicos. La gestión de los bosques en una condición ... -
Multimodel simulations of forest harvesting effects on long-term productivity and CN cycling in aspen forests
The effects of forest management on soil carbon (C) and nitrogen (N) dynamics vary by harvest type and species. We simulated long‐term effects of bole‐only harvesting of aspen (Populus tremuloides) on stand productivity ... -
Multiple pathway succession in coastal Tsuga heterophylla, Thuja plicata and Abies amabilis forests on northeastern Vancouver Island, British Columbia
Sustainable forest practices are often designed to mimic natural disturbance and successional processes, yet succession is poorly understood in many ecosystems. On northeastern Vancouver Island, the ‘disturbance hypothesis’ ... -
Nitrogen source as key factor conditioning responsiveness of Arabidopsis plants to elevated CO2 conditions
The amount of carbon dioxide (CO2) in Earth's atmosphere has exceeded 400 parts per million (ppm) during three continuous months of observations in 2014, which is an absolute record for the last 800,000 years. As a ... -
Nodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis
The symbiotic association between Medicago truncatula and Sinorhizobium meliloti is a well-established model system in the legume–Rhizobium community. Despite its wide use, the symbiotic efficiency of this model has been ... -
Nodule performance within a changing environmental context
Global climate models predict that future environmental conditions will see alterations in temperature, water availability and CO2 concentration ([CO2]) in the atmosphere. Climate change will reinforce the need to develop ... -
Nutritional value of protein from vegetative mycelia of edible mushroom Pleurotus ostreatus
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaThe present work was designed to study the effects of supplementation a control diet with P. ostreatus mycelium for evaluation a nutritional value of mycoprotein and possible cholesterol lowering. -
Nutritional value of raw and extruded chickpeas (Cicer arietinum L.) for growing chickens
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2008) Artículo / ArtikuluaSe realizó un experimento con el objeto de estudiar el efecto de la inclusión de distintas concentraciones (0, 100, 200 y 300 g kg-1) de garbanzo crudo y extrusionado sobre los parámetros productivos, el peso y la longitud ... -
Overexpression of a pine Dof transcription factor in hybrid poplars: A comparative study in trees growing under controlled and natural conditions
In this work, the role of the pine transcriptional regulator Dof 5 in carbon and nitrogen metabolism has been examined in poplar trees. The overexpression of the gene and potential effects on growth and biomass production ... -
Papel de los factores bióticos y las sequías en el decaimiento del bosque: aportaciones desde la dendroecología
El aumento de la mortalidad y la pérdida de vitalidad de los bosques son procesos que afectan a diversas especies de árboles y biomas. Estos fenómenos de decaimiento forestal se han asociado a la interacción de múltiples ... -
The pattern of shikimate pathway and phenylpropanoids after inhibition by glyphosate or quinate feeding in pea roots
The shikimate pathway is a metabolic route for the biosynthesis of aromatic amino acids (AAAs) (i.e. phenylalanine, tyrosine, and tryptophan). A key enzyme of shikimate pathway (5-enolpyruvylshikimate-3-phosphate synthase, ... -
Pea plant responsiveness under elevated [CO2] is conditioned by the N source (N2 fixation versus NO3 fertilization)
The main goal of this study was to test the effect of [CO2] on C and N management in 2different plant organs (shoots, roots and nodules) and its implication in the 3responsiveness of exclusively ... -
Pedogenic, mineralogical and land-use controls on organic carbon stabilization in two contrasting soils
Organo-mineral complexation in soils is strongly controlled by pedogenesis, but the mechanisms controlling it and its interaction with cultivation are not yet well understood. We compared the mineralogy and quality of ... -
Physiological action of herbicides inhibiting amino acid biosynthesis and their sustainable mixtures in Amaranthus palmeri sensitive and resistant to glyphosate
Durante el siglo pasado, la producción agrícola se ha ido incrementando en todo el mundo gracias a la mejora en sus técnicas de manejo. Una de las herramientas más poderosas para alcanzar ese incremento en la producción ...
